One possibility would be to change RDF Schema in some way, perhaps by
modifying the way rdfs:Class, etc., work.  Do we want to include this
possiblity explicitly in the document?  

However, I don't believe that the same-syntax extension is possible without
modifying RDF Schema, and  that would fit into one of the other options.
